Phase-Space Picture of Squeezing via Driven Generalized Parametric Oscillator
Sotirios Baskoutas, Wolfram Schommers
Abstract
In the present work we study the phase space picture of squeezing using the model of the driven generalized parametric oscillator. Exploiting the SU (1, 1)⊕ h (4) algebraic structure of the Wigner operator we find the exact solution of the time dependent Wigner equation as well as the variances of the operators q and p. Due to the fact that we have not any violation of the Liouville's theorem, this model is appropriate to study pure quantum effects (for instance tunneling time) with the classical trajectory molecular dynamics technique.
